3 sources for · 0 against

Cross-linguistic research establishes that human languages trade off information density against speed or length, allowing ultra-sparse or lower-density languages to preserve overall information rates through compensatory mechanisms like faster speech rates.

Evidence for · 3
Different languages, similar encoding efficiency: Comparable information rates across the human communicative niche
2019 · cited by 184
The study demonstrates that languages with low information per syllable (sparse density) compensate through faster speech rates to maintain comparable overall information rates (~39 bits/s).

The analysis

The retrieved papers (such as 0, 5, and 9) directly demonstrate that natural human languages balance structural differences—specifically, variations in information density per syllable or word—through inverse adjustments in speech rate or efficiency, thereby maintaining stable information transmission rates per second.

Research shows that human languages exhibit trade-offs between information density and communication speed across the communicative channel.
Speaking Rate, Information Density, and Information Rate in First-Language and Second-Language Speech
2019 · cited by 5
Cross-linguistic comparison of L1 speech confirms a trade-off between speaking rate and information density, where low-density languages tend to be spoken at faster rates.
